Fitness is not a fad, and the Sirrus proves you're taking your fitness journey seriously. The Sirrus combines our premium aluminum frame with a durable component package and easy-to-maintain rim brakes to deliver a comfortable and fast ride. As you push yourself to reach your goals, the Sirrus will be a powerful ally to have on your health and wellbeing team.
  • The frame is engineered and designed with Fitness Geometry, helping you ride more efficiently in a position that will see you riding comfortably, mile-after-mile, while the Body Geometry Targa Sport saddle is designed for fitness riders and assures blood flow to sensitive arteries.
  • Wide and stable-handling 700x32mm Specialized Nimbus tires have a fast and smooth tread, and feature Flak Jacket puncture protection.
  • The reliable and sturdy, A1 Premium Aluminum frame features rack and fender mounts, allowing you to carry gear or to fend off road spray in inclement weather.
  • Reflective graphics are strategically located on the bike in order to increase your visibility to other riders and motorists in low-light conditions.
